Africa Challenge: Access to Affordable Energy Services 12% of the global population but consumes only 3% of all electricity produced

Electricity generation - World (Source: International Energy Agency – Key World Energy Statistics 2008)

Electricity generation per region (Source: International Energy Agency – Key World Energy Statistics 2008) 3.1%

Heading Eskom’s climate change strategy

Eskom’s climate change strategy Eskom’s climate change strategy: commitment to reduce our greenhouse gas emissions outlines our view on the impacts of climate change on our business and people and therefore what strategies we require to pro-actively manage these impacts Although the amount of CO 2 that we emit will increase in the short- to medium-term, we are committed to assessing options to retard that rate of increase Our intent is to decrease our relative CO 2 (Mt CO 2 /MWh) footprint - until 2025 Beyond 2025, we will continually reduce absolute emissions in support of national and global targets This will be done by investing in aggressive energy efficiency programmes and lower carbon-emitting technologies, as these technologies become available and meet the feasibility requirements

Eskom’s climate change strategy:

commitment to reduce our greenhouse gas emissions

outlines our view on the impacts of climate change on our business and people and therefore what strategies we require to pro-actively manage these impacts

Although the amount of CO 2 that we emit will increase in the short- to medium-term, we are committed to assessing options to retard that rate of increase

Our intent is to decrease our relative CO 2 (Mt CO 2 /MWh) footprint - until 2025

Beyond 2025, we will continually reduce absolute emissions in support of national and global targets

This will be done by investing in aggressive energy efficiency programmes and lower carbon-emitting technologies, as these technologies become available and meet the feasibility requirements

Eskom’s six point plan on climate change Diversification of the generation-mix to lower carbon emitting technologies Energy efficiency measures to reduce demand, greenhouse gas and other emissions Innovation through research, demonstration and development Investment through carbon market mechanisms Adaptation to the negative impacts of climate change Progress through advocacy, partnerships and collaboration

Heading History of renewable energy in Eskom

History of Eskom – renewable energy (1) The Encyclopaedia of Southern Africa, records that "an electric device" was used in South Africa in about 1809 Gold was found in 1873 at Pilgrim's Rest - two small [6 kW] hydroelectric generators were in use at the Pilgrim's Rest gold mines in 1892 and another one [45 kW] in 1894 - used to power the first electric railway Table Bay Harbour illuminated from April 1882. (Photo: State Archives Ref E 8661) The first electrified railway in South Africa at Pilgrim's Rest.

History of Eskom – renewable energy (2) Kimberley switched on electric street lights in 1882 making it the first city in Africa to be illuminated in this manner - London still relied on gas lamps for street lighting The notion of a central electricity undertaking gained the support - establishment of the Victoria Falls Power Company Limited (VFP) on 17 October 1906 - intended harnessing the power of the Victoria Falls to generate the electricity (but was coal-based)

History of Eskom – renewable energy (3) The Government Gazette of 6 March 1923 announced the establishment of The Electricity Supply Commission (Escom), effective from 1 March 1923 The hydro station in the Sabie River came into commercial operation in mid-1927 . The Sabie River Gorge hydro station was the first station designed by Escom engineers 1965-1967: Cahora Bassa hydro-electric power station on the Zambezi River, in Mozambique (between South African and Portuguese governments) It was intended to supply electrical power along a 1 400 km route to South Africa - first power transmitted from Cahora Bassa in May 1975
